$5 battle chest wow

so theres a promotion for wow now.
$5 only for an account upgrade to battle chest.
i was thinking making like 10 accounts and upgrade them all to battle chest. and just let it sit there. or use to bot low level mines or herbs.
i was thinking let it sit for like 6month or more.
then when a new benefit of SoR comes. i can SoR those account.
Maybe blizzard will offer a free upgrade to MoP or something like that.
like the SoR benefit now

[/size]I actually had a similar idea I was just thinking about today..then I got to wondering..without upgrading to MoP..one way or another..how would you get the low level herbs & ores off those accounts?

It seems Blizzard would need to reset these almost yearly so I think that this can be a good buy, but it's a long term investment. I might buy a few and bot on them and let them sit aswell after the first month.
